Collisions between large cetaceans and commercial vessels
Since the advent of navigation, marine animals have been obliged to share sea and ocean surfaces with humans. If ships are able to collide with each other in this space, it is also possible for them to collide with cetaceans. These collisions occur in waters all around the world, and can result in the death of the injured animal. In the Mediterranean, the scientific community is particularly worried about the status of the fin whale and the sperm whale, whose natural mortality rates could be seriously augmented by these accidents. Nowadays, with the extensive use of high speed craft, navigation companies and passengers are also suffering the consequences of such accidents. In fact, ports and coastal towns are also confronted by delicate health-related and financial issues when the carcass of a 20–80 tonne animal is brought in by a ship or the currents. Many studies address this issue, but the exact causes of these events, their impact on cetacean populations and how to avoid them, are far from being understood.

There are many factors contributing to the causes, consequences and potential solutions to this problem, which make it an inexhaustible subject. Reduction of the risk then will not happen through one single study but through many, each tackling the problem in a specific field and targeted region. Since the year 2000, in partnership with navigation companies and scientific institutions, Souffleurs d’Écume has been involved in a programme aiming to reduce risks of collision in the Mediterranean. This programme comprises applied research work (implementation of specific observation protocols), development of technical instruments for the use of navigation companies (REPCET) and training of navigation professionals.
